CHAPTER 3 Installation
4) Robot overrun during impacts with mechanical stopper
A urethane damper is installed to absorb the shock when an impact occurs
with the mechanical stopper, so a certain amount of overrun occurs when
the robot strikes the mechanical stopper. Use caution and take overrun
into account since the end effector may interfere with the robot body and
peripheral equipment or the robot body may interfere with the peripheral
equipment. Maximum overrun amounts are listed below (for normal opera-
tion, maximum load mass, maximum speed).

Note: Here, ° (deg.) is the overrun angle at the X-axis and Y-axis joints.
1. When the robot strikes the X-axis or Y-axis mechanical stopper or
another object, or when the R-axis collides with an object, speed reduc-
tion gears are locked while being meshed if the collision impact is large.
If this happens, please contact our sales ofce or dealer.
2. When the robot strikes the Z-axis upper mechanical stopper excessively,
the urethane damper may be splayed beyond the retaining ring. In this
case, return the urethane damper to its original state.
